Definitions
- the present invention relates to an arrangement of a plurality of moistened non-woven cosmetic pads which are stape-shaped in a largely evaporative sealable packaging container for delivery to the end user, the pads having on average a moisture content of at least 200% of their dry weight.
- melt-blown fiber layers in which the endless extruded fiber strands are stretched under hot air and deposited on each other in the unconsolidated state and thereby connected at the points of contact, can be a structurally stable structure of a pore size of 20 to 60 considered to be advantageous, where the liquid of the wet wipes can also be stored permanently.
- a structurally stable structure of a pore size of 20 to 60 considered to be advantageous, where the liquid of the wet wipes can also be stored permanently.
- Such a structure was, however, j edoch the requirements placed on moistened cosmetic pads do not do it justice.
- US Pat. No. 6,315,114 Bl also discloses a stackable arrangement of wet wipes in an evaporation-inhibiting sealable packaging container, the wipes being spunbond webs, ie nonwovens of continuous fibers of diameter less than 18 ⁇ m. It is to be achieved in these relatively thin wet wipes of staple fibers in addition to a uniform moisture content improved tear strength and durability against fraying and the delivery of a minimum amount of liquid. For moistening a stapeiförmige arrangement is acted upon as a whole with a quantity of liquid. These wipes would not meet the requirements of moist cosmetic pads.
- US Pat. No. 4,608,437 and the US Pat. No. 4,649,695 resulting therefrom relate to a manufacturing method and a production apparatus for conventional moistening of an endless tissue web, that is to say a wet-laid fiber web structure, as used for wet wipes for personal care. Longitudinal sections are cut out of this web and arranged in the form of a stack in a packaging container.
- These documents are based on a state of the art, according to which structurally stable wet-laid tissue webs were guided endlessly through a liquid bath. Further information can not be found in these publications.
- the present invention has for its object to provide an arrangement of nonwoven cosmetic pads of the type mentioned, which are characterized by a good fluid absorption behavior and a good permanent moisture or fluid retention capacity, wherein the achievement of a permanently uniform moistening of the pads within the stacked arrangement is desired.
- the pads comprise a fiber structure of staple fibers and are individually moistened and within the arrangement have a uniform moisture content to the effect that the difference in the average moisture content of the upper and lower Quarter of the stack arranged pads is at most 30% of the average moisture content of all pads of the stack.
- the arrangement of a plurality of moistened nonwoven-based cosmetic pads advantageously shows a difference between the average moisture content of the pads arranged in the upper and lower quarters of the stack of not more than 25%, in particular not more than 20%, more particularly not more than 15%, based on the mean moisture content of all the pads of the pile.
- the amount of liquid, in particular at least 300% can advantageously also at least 250%, especially at least 320% have their dry weight, being more particularly at most 400% of the dry weight is at most 500%, especially at most 450%, of a respective pads.
- statistical methods are used in the determination of the moisture content, in particular of a predetermined number of pads, in particular of all pads, the moisture content is determined and of which the mean value is formed.
- the inventive arrangement of the pads is distinguished from known arrangements with a considerable but not excessive moisture content as mentioned by the claimed moist distribution is maintained: it is not, as in some known pads, to an extreme accumulation of the liquid at the bottom of the Packaging container and associated with a proper soaking the bottom pads.
- the formation of the fiber structure from air-laid staple fibers and the individual moistening of the pads is of essential importance here, which is made responsible for the fact that the moisture content can be kept in the claimed area even four weeks after moistening.
- the pads have a weight per unit area of 40-350 g / m 2 , in particular of 60-250 g / m 2 , in particular of 100-200 g / m 2 and more particularly of 100-140 g / m 2 .
- They further advantageously have a thickness of 0, 6 - 4, 0 mm, in particular from 0, 8 - 3, 5 mm, in particular from 1, 0 3, 0 mm, and more particularly from 1, 2 - 2, 5 mm, measured at a test pressure of 0.5 kPa.
- the pads according to the invention show a good moisture retention capacity, ie that under load (which is the case with the use of the pad, for example, when rubbing off the skin) the child is sufficient, but moderately gives off fluid.
- a centrifugation step follows at 250 rpm for 4 minutes.
- the difference between the liquid dispensed in the centrifugation step (determined as the difference between the initial weight of the moistened pedestal before the centrifugation step and the weight of the pad after centrifuging) and The moisture retention capacity is expressed as a percentage of the weight of the liquid remaining in the patty, based on the weight of the liquid used
- staple fibers have a length of 3 to 60 mm proven.
- Staple fibers are understood to be fibers of limited length, which may be man-made fibers, ie fibers made industrially from natural or synthetic polymers, and natural fibers. If man-made fibers are additionally used as staple fibers, then, in an advantageous embodiment, they can also have lengths of 15 to 40 mm, in particular 15 to 25 mm.
- the length of natural staple fibers, such as cotton fibers are advantageously 9-15 mm, in particular about 12 mm.
- the above-mentioned chemical fibers as staple fibers may advantageously comprise micro staple fibers or be micro staple fibers.
- micro staple fibers here means that these fibers have a thickness of ⁇ 1 dtex.
- Micro staple fibers may advantageously be polyester (PES) fibers or viscose fibers (although viscose fibers are made of natural cellulose molecules, they are synthetically processed to form fibers).
- PET polyester
- viscose fibers are made of natural cellulose molecules, they are synthetically processed to form fibers.
- micro staple fibers When micro staple fibers are used, they are advantageously hydrophilized on their surface in order to provide good liquid uptake capability.
- the indication of the weight fractions of the fibers is always based on the not yet moistened fiber structure to understand.
- the fiber structure contains up to 72% by weight, in particular 15 to 65% by weight and more particularly 50 to 65% by weight, of cotton fibers. These are preferably cotton noils.
- the fiber structure of the pads additionally comprises heat-meltable binding fibers, likewise as staple fibers, in particular in a weight percentage of 10 to 20% by weight, in particular 10 to 18% by weight and more particularly 10 to 15% by weight.
- Bin.defasern can be, advantageously be multi-component fibers, in particular bicomponent fibers, in particular a sheath / core arrangement of the two components.
- multicomponent fibers advantageously have a fiber thickness of 1.3 to 10 dtex, in particular of 1.3 to 3.0 dtex, and a fiber length of 3 to 60 mm, in particular of 40 to 60 mm.
- Preferred bicomponent fibers may be polyester (PES) / copolyester (CO-PES) bicomponent fibers.
- the melting point of the heat-fusible bonding fibers or the low-melting component of the multicomponent fibers as bonding fibers is less than the melting point of additionally used staple fibers or micro-staple fibers.
- a preferred composition of the fiber structure of a pad for forming the device according to the invention comprises
- micro-staple fibers 30% by weight of micro-staple fibers, 9 to 17% by weight of binder fibers and 58 to 66% by weight of cotton fibers.
- the pads which are fibrous nonwoven structures, can be water-jet needled for solidification, which in particular can only detect near-surface areas of the fiber structure or can also mean a continuous needling of the pads.

- a removal opening in the manual access area, which is in particular resealable, is above the
- Overlapping area of the pads provided.
- oval pads are arranged overlapping in the two stacks, so that the packaging container has an outer shape approximating an eight-shape.
- the pads in an upper and lower quarter or in the outer quarters of a stack this does not necessarily require that the number of pads in a stack be a multiple of 4. For example, if there are 19 pads in an array, then the outer quarters are determined by dividing the number of pads by 4, yielding the result "4 - remainder 3".
- the invention also includes a method of manufacturing an array of a plurality of moistened cosmetic pads wherein an airlaid fibrous web is formed, the pads are shaped from this fibrous web and the pads are then individually wetted.
- the pads are exposed in a still isolated state immediately after or during moistening a pressure, so that the pads are compressed to even out the liquid distribution in Päd.
- the pressure exerted on the pads pressure is 0, 5 mbar to 10 bar.
- thermoplastic fibers for example of polyester, polyamide, polyacrylic, polyolefins, polyurethane, as well as multicomponent fibers, in particular as bicomponent fibers, and preferably as microfibers with a fiber thickness of ⁇ 1 dtex, more preferably micro staple fibers of a length of at least 7mm include.
- the pads according to the invention preferably have a circular shape, preferably also oval shapes, as well as square or rectangular shapes are conceivable.
- the circular pads have a diameter of 5-7 cm.
- Oval pads cover an area of preferably (60-80 mm) x (80-100 mm).
- Square pads preferably have a side length between 60-80 mm, in particular 75 mm.
- Rectangular pads have an area with dimensions preferably (70-100 mm) ⁇ (90 mm-120 mm), in particular (85 mm-95 mm) ⁇ (105 mm -115 mm).
- a further independent aspect of the invention is also an arrangement of a plurality of moistened nonwoven cosmetic pads which are stape-shaped in a packaging container which is largely closable against evaporation, the pads having on average a moisture content of at least 200% and at most 500% by weight of their dry weight , the pads comprise a fiber structure of staple fibers, have a thickness of 0, 6 - 4, 0 mm and are individually wetted.
- these pads have on average a moisture content of at least 250%, in particular of at least 300%, in particular of at least 320% and in particular of at most 450%, in particular of at most 400% of their dry weight.
- These pads advantageously have a thickness of 0, 8 - 3, 5 mm, in particular of 1, 0 - 3, 0 mm, and more particularly of 1, 2 - 2, 5 mm.
- pads advantageously have one or more of the other features mentioned above, in particular. in terms of fiber composition (type of fiber, percentage composition), length of fibers, hardening (water jet, thermal bonding, embossing), stacking, impregnation, and the difference in average moisture content in the upper and lower quarters stack of pads arranged.
- Figure 1 is a schematic representation of a device for individual moistening of cosmetic pads and for stacking these pads.
- An advantageous composition of nonwoven-based cosmetic pads comprises a staple fiber fiber structure.
- the composition of these staple fibers is advantageously given by 25% by weight of microfibers of polyester, in particular of a preferred length of 18 mm and a fiber thickness of 0.9 dtex, and 13% by weight of bicomponent fibers as binder fibers, advantageously polyester (PES) / Copolyester (CO-PES) bicomponent fibers, having a preferred length of 51 mm and a fiber thickness of 2, 2 dtex, and 62% cotton combs having as natural fibers a fiber length of about 12 mm.
- the staple fibers mentioned above are laid down ("airlaid") as a dry fiber mixture to form an endless nonwoven web.
- nonwoven web pads of a per se arbitrary, in particular round or oval shape are then formed, in particular punched out. These pads are moistened individually after forming from the fiber web, so acted upon with a previously metered amount of liquid and then arranged to form a stack in a packaging container.
- the pads formed out of the nonwoven web can for example be stored in the form of a stack and fed in this form to a device for individual moistening of the pads.
- a pedestal is removed from the magazine-mounted arrangement 4 and fed to a moistening station 6 by means of a suction gripper device 2 shown schematically in FIG.
- the pedestal is in a trough-shaped receptacle 8 which is preferably adapted to the pad mold and into which a certain amount of previously metered liquid is supplied by a metering device (not shown).
- a precisely metered amount of liquid is absorbed by the person disposed in the moistening station 6 Päd or introduced into the Päd.
- the moistening of the pad takes place under a pressure, not shown.
- pressure of 0.5 mbar to 10 bar is used. Accordingly, it is also possible to use vacuum.
- the pedestrian is grasped by the suction gripper device 2 and removed from the moistening station 6 and then transferred to a depositing device 10, which deposits one pedestal after the other to form a stape-shaped arrangement 12.
- a depositing device 10 which deposits one pedestal after the other to form a stape-shaped arrangement 12.
- the storage and the formation of the stack-shaped arrangement 12 takes place directly in a subsequently evaporative-resistant closable packaging container 14. It would also be conceivable that the stacking takes place outside of such a packaging container and the stack thus formed is then inserted as a whole in a packaging container.
- a number of 20 pads of the type described above were prepared from an air laid nonwoven fabric having a basis weight of 115 g / m 2 and a thickness of MO ⁇ approx. 1, 3 mm (measured under a test pressure of 0, 5 kPa) formed out.
- the pads have an oval shape with 70 mm x 90 mm diameter.
- the dry weight of each of the 20 pads was determined by single weighing and determined to the nearest 2 decimal places in grams.
